| Outline of Annual Research Achievements |
昨年度までに多くの低次元物質のその場観察測定を行ない、物性との関連を調べる研究を行なった。とくに高温観察は試料汚染を軽減し、正確なデータ取得に有益であった。
新規二次元物質は興味深い性質を示すことが明らかになった。例えば、PdSe2層状物質はSe原子空孔を通して、予想されていないPd2Se3層に変化することがわかった。またBN層に成長したNbS2はスーパセル再構成を示した。二次元アモルファスカーボン物質においては原子ごとに異なるK吸収端の測定に成功した。これらの成果はPRL誌などに発表された。
また低温観察においては、０次元物質である量子ドットのバンドギャップの粒子形やサイズ依存性を調べることに成功した。これらの成果は現在投稿中である。

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The research supported by JSPS went quite well with the proposal so far. We have achieved the required data for the designated goal in the first and second phase of the supported period as proposed. We have published a number of first authored papers in this subject with the acknowledgement from the JSPS financial support, two more under review, and more than eight co-authored papers that is either published or under review.

| Strategy for Future Research Activity |
1. Continue to collaborate with the synthesizing group to find suitable 2D materials for in-situ study. Meanwhile, continue the research on exploring the physical properties on novel 2D materials by existing techniques, such as high resolution STEM and EELS spectroscopy. We collaborate with NTU and NUS in Singapore.
2. Investigate the possibility for in-situ monochromatic EELS in 2D and 0D materials by expanding the high resolution imaging and EELS technique to more practical materials that also suitable for in-situ study, like pervoskite quantum dots and thin film.
